How does pickled herring taste?

Pickled herring has a distinct flavor that is both tangy and slightly sweet, often with a hint of spice depending on the marinade used. The fish itself is tender and oily, providing a rich mouthfeel that contrasts with the acidity of the pickling solution. The overall taste experience can be quite complex, with notes of vinegar, sugar, and sometimes herbs or onions. It's a popular dish in many cultures, often enjoyed with bread or potatoes.
